hard, sharp meter probes that can withstand being used to scratch components?
thom:
Howdy everyone,
I repair lightning damaged devices for a living, and part of the diagnosis process is, for example, testing a row of 30 mosfets, and each one that tests bad gets a mark scraped in it with my probe tip so I know which ones to pull. I've had dozens of different cheap old aliexpress probes over the years, some with properly hard sharp tips, most with soft tips, but they all get worn down and sharpened regularly. I am wondering if there are any sharp probes with metal hardened enough to suit this specific use case?
alternatively, if you think there is a more efficient method for efficiently marking chips as I read them without having to drop my probes and pick up a pen, I am all ears!
I've got a pomna 6431 set coming with the hopes that the SS tips are higher quality than the chinesium I am used to

The Probemaster gold-plated SS probes are really sharp. They'll stab you quite easily and they come with little safety covers on them to keep them from poking through their packaging. I can't say how long they will stay that sharp being used as you state, but mine are still dangerously sharp after years of normal use.

I get the old dental picks and grind the ends. Add wire and some shrink tubing.
If you want to just buy a set, I have some stainless like these that can be sharpened as well:

Hi Joe, do you mean you have a 3rd party source for ponomoa compatible SS tips? I bought the full set, and if the SS tips are good, it would be nice to be able to buy just those instead of having to buy the 10 pc kit!
as an aside, I recognize you from youtube, your videos are fantastic, thanks for the effort you put in!

Like Bdunham7 said, just buy Probemasters.. They are very good quality, very sharp (scarry), made of stainless steel.
Pomona 6341 are expensive piece of crap. I have both and Probemaster is superior quality..
